MEASURING-ROLLER,

To all whom it may concern:

Be it known 5 that I, GREENE CARLTON HOSCH, a citizen of the United States, residing in the city ofSt. Louis and State of Missouri, have invented new. and useful Improvementsin Measuring-Rollers, of which the following is a specification.

This invention relates to fabric measuringand cost computing machines, and particularly to the type of such machines which employ a measuring roller having a special coating or clothing for its face. The surface of this covering must develop a certain amount of friction to insure that there will be no slip of the measured fabric on the surface of the roller when the fabric is being drawn. through the measuring machine.

The composition most suitable for this covering or clothing of such a roller, is a mixture of carborundum dust and sodium silicate, but the friction-developing propertyiof this composition has a certain (11S:-

advantage in the practical operation of the machine which arises in introducing the edge of the fabric into the measuring gap.

The object of this invention is to overcome this disadvantage, and to produce a roller of special form which will facilitate the application of the shell to it, and, which, atthesame time, will overcome. the disadvantage inherent in such a roller.

The invention consists in the novel fea tures of parts to be particularly described hereinafter, all of wh1oh contribute to produce a simple and efficient measuring roller for a fabric measuring and cost computing machine. A preferred embodiment of my invention will be articularly described in the following specification, while the broad scope of my invention will be pointed out in the appended claims. 7

In the drawing, which fully illustrates my invention,

trating how the form of the roller may cooperate to facilitate the application of the clothing or shell to the core of the roller.

Referring more articularly'to the parts, the measuring rol er comprises a metallic core 1 which may be formed of aluminum, said core having a transverse head 2, the inner face of which is provided with a counter bore 3 to form a bearing for the core, seating on the end of an arbor 4 which is fixed in a vertical wall 5 of the frame of the machine. This arbor is. of tubular form and carries a shaft 6 for driving indicating mechanism, (not illustrated), the outer end of the shaft being rigidly secured in a hub 7 formed on the head 2 of the core 1. The cylindrical surface of this core is provided with a covering or clothing in the form of a shell 8, which is in the. present instance, formed of a suitable composition, such as sodium silicate and emery and the outer end of the core 2 is provided with an outwardly projecting flange 9 which covers the end of this shell 8. I i

A presser roller cchperates with the measurin roller b it w en the fa hric is being measured.

The flange 9 performs a double function, the first of which arises fromthe fact that it operates as a stop for the shell in being placed on the core. One manner in which this flange may perform this function will be described, when the composition shell is molded directly onto the roller.

Referring particularly to Figs. 3 and 4, 10 represents the base plate of a mold, which also includes two cooperating sections 11 and 12 which come together on vertical faces 13 provided with dowel pins 14, and cooperating sockets 15 carried on the opposite mold section. The core 1 of the roller is set up on a vertical axis in the center of this mold with the flange 9 seated on the bottom of the mold. The internal diameter of the mold is very slightly greater than the diameter of this flange 9.

Before pouring the composition into the mold, the inner face of the mold is provided with a tubular liner 16 of paper. The upper end of the core 1 is then provided with a cap 17 which forms a covering for the end of the core and prevents the composition from passing into the interior of the core when the composition is being poured. The composition, which is preferable for forming pressing the fabric against I'event-in an relative r this shell, is any of the well known mixtures of carborundum dust and sodium silicate.

This composition 18 is poured from a ladleuring machines are often used for measuring delicate-silks and fine ribbons, and if a roller having. a, covering suitable for developing '2 sufiicientfriction is employed,'havingan exposed end, the exposed endis more or less rough, and tends to injure the edge of such finef mat'eriall ,whennbei'ng dragged over the I end"of -the 'roller in guiding the material into the measuring gapibetween the measur- 25 inglrollerand the presser roller. In Fig. 1 the outline of the presser roller is indicated at; 21 which shows approximately the positionof thefpresser roller whenseparated from the measuring roller to permit the introductionofthe material to be measured. As'this gap is notwide, it is customary for the operatoryin' inserting the fabric, to hold the extreme edge of the ribbon or cloth againstthe endof the roller,then elevate the 3 5 edgeinto the gap, and-then drag-the material over'the end: of the roller, further into i. =e i When-:the'roller is constructed in accordance with this invention, the polished metal surface of the flange quickly guides the edge of the material into the gap and no injury can be done to the surface of the material by drawing it over the edge of the flange in pulling the material well into the gap. In practice, the outer surface of the shell is turned accurately to the desired pre-determined diameter; The outer diameter of the flange 9 should be about l-100 of an inch smaller than the diameter over the shell.

What I claim and desire to secure by Letters Patent is:

1 In a cloth measuring machine, a measuring roller consisting of a metallic core with amolded shell of composition on the cylindrical face thereof, said shell having a rough outer face, said core having a flange at one end only operating as a stop to limit the movement of the composition shell when being placed on the core of the roller, and covering the end of the shell to prevent the edge of the cloth engaging the same when being passed into the machine and along the surface of said roller.

2. In a cloth measuring machine, a measuring roller, consisting of a metallic core with a shell on the cylindrical face thereof, said shell having a rough outer face, said core having a flange at one end only operating as a stop to limit the movement of the shell when being placed on the core of the roller, and covering the end of the shell to prevent the edge of the cloth engaging the same when being passed into the machine and along the surface of said roller.

In testimony whereof, I have hereunto set my hand. 1
